Client Experience

  • As a project management leader for one of the largest energy infrastructure companies in North America, my priority is to guide projects to successful completion, in order to deliver financial and operational excellence to our client base. Allison Companies has proven one of the best contracting agencies I have had the pleasure of engaging. Their dedication and work ethic have proven an invaluable resource, time and time again. In one of our most recent collaborations, our teams encountered various environmental challenges through marshland terrain and weather-related issues, including snow. Regardless of the circumstances, Allison persevered and advanced our project effectively and in a timely manner. Their proven and consistent communication system provided our team with invaluable updates and created a fully integrated team scenario between our companies. I highly recommend their services, and look forward to working with their team in the future.

  • In Feb 2017, Allison provided a production platform for our MP 270B location. The scope included providing all platform structural and facility engineering, pipeline engineering, providing all materials, fabricating piping and vessels, structural repair and re-certification of a 4 pile platform, Instrumentation and electrical, commissioning as well as logistics management and offshore installation and platform start-up. In todays environment, it was imperative that Castex reduce its schedule and cost risk, so we decided to contract with Allison based on a “Fixed Price” EPCIC basis. This contracting strategy allowed Allison full control of deliverables and schedule, which ultimately reduced our exposure and helped our ROI by getting the well flowing quicker. The
    project was completed on time and budget without any incidents.
